infra.aop.interceptor.ExposeBeanNameAdvisors

public abstract class ExposeBeanNameAdvisors
extends Object

Convenient methods for creating advisors that may be used when autoproxying beans created with the IoC container, binding the bean name to the current invocation. May support a bean() pointcut designator with AspectJ.

Typically used in auto-proxying, where the bean name is known at proxy creation time.
